The PNG format is *not* lossy. From
"""PNG is an extensible file format for the lossless, portable,
well-compressed storage of raster images. PNG provides a patent-free
replacement for GIF and can also replace many common uses of
TIFF. Indexed-color, grayscale, and truecolor images are supported,
plus an optional alpha channel for transparency. Sample depths range
from 1 to 16 bits."""
